The countries that grow the most illegal Opium are Pakistan, Burma, Thailand, and Afghanistan, which is also the worldâs top supplier of Opium. Opium can also be grown in places like Mexico and Columbia. Afghanistan accounts to over 90% of the worldâs grown Opium.
This equation, I = V / R, tells us that the current, I, flowing through a circuit is directly proportional to the voltage, V, and inversely proportional to the resistance, R. In other words, if we increase the voltage, then the current will increase.
As the wire in the coil has resistance, the current is determined using ohms law, I = V/R. The current is proportional to the voltage, and inversely proportional to the resistance. Note that the resistance increases somewhat as the wire heats up.There can only be more voltage and less current by changing the coil.nswers. Best Answer: The following is in relation to an electromagnet, but generally applies to magnetic fields generated by electric current. The magnetic field is proportional to the current in amps and the number of turns of the conductor about the core (ampere-turns).
